Maybe they should post a sign that says - "USE WHATEVER DOOR APPEALS TO YOU - JUST PUSH THOSE OTHER PEOPLE OUT OF YOUR WAY." But that would be superfluous since everyone is already doing that.
One place where you cannot use whatever door you want is heaven. Jesus said,
I am the door. If anyone enters by Me, he will be saved, and will go in and out and find pasture. (John 10:9 NKJV)He also said,
“Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. Because narrow is the gate and difficult is the way which leads to life, and there are few who find it. (Matthew 7:13–14 NKJV)There is one door by which we gain entrance to heaven and it is Jesus Himself. There is one gate and one way that leads to eternal life - and it is not the way most traveled.
This is a message that is not popular and not politically correct. It doesn't meet the postmodern standard of tolerance because it doesn't affirm everyone's views as equally truthful. This claim of exclusivity is seen as out of step with multiculturalism in our pluralistic society.
But I didn't make it up. I am just quoting it. This is from the Bible. God is speaking. He doesn't seem to feel constrained by the dictates of our postmodern sages. He also says,
(Proverbs 16:25 NKJV) There is a way that seems right to a man, But its end is the way of death.So you will need to choose. You can choose what you want. But your choice is not "right" just because it is your choice. Believe or disbelieve what the Bible says, but there are consequences.
